Need help in ID'ing this badge: This is the info, badge made by the Germans, during WW2, and issued to Royal Marines prisoners of war. The badge is 46mm across, die-struck from a grey metal alloy and fitted with a horizontal, brooch-type fastener. Why the Royal Marines should be singled out to have badges made for them in P.o.W camps, I cannot guess, unless the prisoners themselves took the initiative. Any help on the ID and if story is true. Thanks.
